To generate the equation we set up the factors
(x+3) * (x-1) * (x-2) which equals
x^2 + 2x -3 * (x-2)
x^3 +2x^2 -3x -2x^2 -4x +6 equals
x^3 -3x -4x +6 which equals

x^3 -7x +6

The diameter of the larger circle is 10.5 cm. The diameter of the smaller circle is 4.5 cm.

blondinia [14]

4.5 / 2 = 2.25cm radius for the smaller circle

3.14 (pi) × 2.25² = 15.89625cm²

10.5 / 2 = 5.25cm radius for the larger circle

3.14 × 5.25² = 86.54625cm²

86.54625 - 15.89625 = <span>70.65cm</span>²

The answer is 70.7cm².
